Advanced solutions for lighting control and driver electronics 2 3 The lighting industry is undergoing a major transformation, driven largely by concerns over climate change and the desire to use energy resources more efficiently. Governments and consumers alike are setting incandescent lights aside, switching to newer, more energy-efficient technologies like compact- fluorescent lamps (CFLs) and solid-state lighting (SSL). These new technologies are, indeed, much more energy-efficient, but they 9re also much more challenging to design, since they require complex driver and control electronics.

That 9s where NXP comes in. NXP & energy-efficient lighting } Proven innovation } Proven efficiency } Proven reliability Making it easy As one of the first semiconductor companies to recognize the growing importance of energy- efficient lighting, we 9ve been supplying complete lighting solutions to some of the largest and most innovative lighting companies for more than 20 years. Now, we 9re opening up our portfolio, offering our proven, highly integrated ICs for lighting control and driver electronics to a much wider audience of OEMs and ODMs.

We 9ve even established a dedicated lighting group, so our customers get the optimized solutions and detailed application support they need to be competitive. Offering integration and support We 9ve made ... more. less.

lighting a strategic focus area and devote a substantial portion of our R&D resources to developing new ways to save energy and simplify design. Our industry-leading GreenChip ICs, for example, are the basis for many of our lighting solutions, and bring new degrees of power management to lighting applications. We consistently set the bar for integration, finding new ways to reduce form factors, and we offer extensive support tooling, for the fastest, simplest design-in possible. Equipped for economies of scale We offer large-scale production capacity and support all the leading formats, including CFL, SSL, HID, and TL. We apply the same best-in-class technical and industry practices across the board, no matter what the technology, so you get a full- service partner that delivers true innovation 3 like dimmer compatibility 3 while simplifying your logistics and reducing your supplier base. This all means we can offer a complete range of solutions for lighting control, from advanced, high- energy-saving integrated solutions, to cost-efficient discrete solutions based on our broad range of semiconductor components. The right technology for every application We offer advanced, cost-effective control and driver ICs for every application, from home and office to retail and street lights. Saving energy at home In the past decade, CFLs have become a popular choice for residential lighting. SSL is starting to make its way into the home, too, and shows great promise for the future. NXP offers cost-effective driver solutions for both technologies. Giving retail revenue a boost Shop owners use lighting to draw people in and show off the merchandise. They 9re looking for good, consistent white-color rendering that 9s as close as possible to natural daylight. Reliability and longevity are also important, since they help reduce maintenance and replacement costs. HID and SSL are excellent choices, and NXP has innovative options for both. Making work spaces more efficient Offices and industrial sites need general lighting, localized lighting, and local task lighting. HF TL fluorescent is an ideal choice, because its bright white light and good color rendering minimize eyestrain, while its consistent performance over a long life reduces cost. HF TL can also dim light in unoccupied areas, for added energy savings. NXP has the right control functions for HF TL. Keeping streets safe Cities around the world are switching to low-energy lighting for their street and highway networks. Advanced dimming capabilities allow large areas to be dimmed during quieter periods, for reduced light pollution and added energy savings. Lights can be set to brighten automatically when there are cars or people present, so everyone stays safe. HID and SSL are popular choices, and NXP has energy-efficient solutions for both technologies. 4 5 UBA2021/UBA2025 integrated drivers for high-power CFL Both devices include a half-bridge power circuit, a feed-forward circuit (constant lamp power over mains voltage variations), a high-voltage level-shift circuit, an oscillator function, a current-control function, a timer function, and protections.
